A07584
A07585
Position setting value activated
The alarm automatically disappears with BI: p2514 = 0 signal.
A07587
A07588
Position actual value processing
does not have a valid encoder
An encoder data set has been assigned, however, the encoder data set
does not contain any encoder data (p0400 = 0) or invalid data (e.g. p0408
= 0). Remedy: Check the drive data sets and encoder data sets.
A07593
A07594
Value range for position actual
value exceeded
The value range (-2147483648 ... 2147483647) for representing the posi-
tion actual value was exceeded. Remedy: Reduce the traversing range or
position resolution. If required, reduce the traversing range or position
resolution.
A07596
A07597
Reference function interrupted
An activated reference function (reference mark search or measuring
probe evaluation) was interrupted. Possible causes:
•
Encoder fault
•
Reference mark search and measuring probe evaluation simultane-
ously activated (BI: p2508 and BI: p2509 = 1 signal).
•
Activated reference function (reference mark search or measuring
probe evaluation) was de-activated (BI: p2508 and BI: p2509 = 0 sig-
nal).
F07599
F07600
Adjustment not possible
The maximum encoder value times the factor to convert the absolute
position (r0483 and/or r2723) from increments to length units (LU) has
exceeded the value range (-2147483648 ... 2147483647) for representing
the position actual value.
F07801
Motor overcurrent
Check current limits (p0640).
Vector control: Check current controller (p1715, p1717).
U/f control: Check the current limiting controller (p1340 … p1346).
Increase acceleration ramp (p1120) or reduce load.
Check motor and motor cables for short circuit and ground fault.
Check motor for star-delta connection and rating plate parameterization.
Check power unit / motor combination.
Select flying restart function (p1200) if switched to rotating motor.
A07805
Drive: Power unit overload I2t
•
Reduce the continuous load.
•
Adapt the load cycle.
•
Check the assignment of rated currents of the motor and power unit.
F07806
Regenerative power limit exceeded Increase deceleration ramp.
Reduce driving load.
Use power unit with higher energy recovery capability.
For vector control, the regenerative power limit in p1531 can be reduced
until the fault is no longer activated.
F07807
Short circuit detected
•
Check the converter connection on the motor side for any phase-
phase short-circuit.
•
Rule out that line and motor cables have been interchanged.
A07850
A07851
A07852
External alarm 1 … 3
The signal for "external alarm 1" has been triggered.
Parameters p2112, p2116 and p2117 determine the signal sources for
the external alarm 1… 3.
Remedy: Rectify the cause of these alarms.
